Answer 1

Answer:

Ava has to work 43 and a half (43.5) hours to earn $609.

Step-by-step explanation:

Given,

Price of new computer = $1218

Solution,

Ava already saved half amount of price of computer.

Half price = $\frac{1218}{2} =609$

The amount of money that Eva has to earn is the difference of price of computer and saved money.

Amount to be earn = $1218-609=609$

Here we use the unitary method to find out the number of hours.

∵ Ava earns $14 in 1 hour.

∴  Ava earns $1 = $\frac{1}{14}$

∴  Ava earns $609 =$\frac{1}{14}\times609=43.5\ hours$

Hence Ava has to work 43 and a half (43.5) hours to earn $609.
